Thicker than Water by Remi Lebeau

Can she melt the heart of a stone-cold mafia boss?

Amara Moonfall is in way over her head.
When her witch coven is threatened, Amara is forced to go undercover as a bartender at a nightclub operated by the most notorious vampire mafia family in the city.
It’s a dangerous game. Thrust out of her cozy life into a dark underworld, Amara has to conquer bloodthirsty vampires, family feuds…and a captivating mafia boss with a heart of ice.
Celine Côté is the eldest progeny of the most powerful vampire in the city. She runs the family business with an iron fist, but can’t get out from her Creator’s shadow.
Eager to prove herself, Celine goes head-to-head with the rival vampire boss. But she puts everything she loves at risk, including Amara.
Neither of them realize that there’s an even bigger threat.
A threat that will make them question where their loyalty lies…
And whether they will sacrifice it all for love.
